• Force Open – Manually forces the router’s Aux Relay contacts to stay open. This setting
manually controls the device connected to the relay, or can be used to test relay operation.
• Force Closed – Manually forces the router’s Aux Relay contacts to stay closed. This setting
manually controls the device connected to the relay, or can be used to test relay operation.
This setting also allows the router’s Aux Relay to be forced closed and to stay closed until the
open setting [under the Auto VDC , Auto VDC (BTS Comp) or Auto SOC setting] is reached.
Normally, the router’s Aux Relay is open until the closed setting is reached. However, if Forced
Closed is selected fi rst, and then:
– Auto VDC or Auto VDC (BTS Comp) is selected—if the battery voltage is between the open
and close settings after Auto VDC or Auto VDC (BTS Comp) is selected, the relay stays closed
until the VDC open setting (and any delay time) is reached.
–
Auto SOC is selected—if the SOC value is between the open and close settings after Auto
SOC is selected, the relay stays closed until the SOC open setting is reached.
Info: When the Force Open or Force Closed options are selected, the router’s Aux
Relay opens or closes without any time delay.
• Auto VDC – Automatically activates the router’s Aux Relay based on adjustable DC voltage
settings under the SETUP: 01F ARTR Aux Relay menu. The relay uses the Close Volts and
Open Volts settings to close and open based on a low or high DC voltage, and allows the relay
to be con fi gured to activate either as an “active high” or “active low” type relay. This relay
also uses the Close Delay and Open Delay settings to automatically control the relay’s open
and close delay times. (Refer to the SETUP: 01F ARTR Aux Relay menu on pages 24-25 for
more information on these settings.)
• Auto VDC (BTS Comp) – Same as the Auto VDC setting. However, it compensates the
voltage settings based on the battery temperature reading when the BTS (Battery Temp
Sensor) is used.
Example : The Open Volts setting is 26.2, the Close Volts setting is 25.1, and the BTS
temperature is 50°F/10°C (a voltage compensation of +0.9 volts * ). In this scenario, the
router’s Aux Relay opens when the actual battery voltage is 27.1 (26.2 + 0.9) and closes
when the actual battery voltage is 26.0V (25.1 + 0.9).
* – Refer to the “BTS Temperature to Charge Voltage Change” chart in your inverter owner’s
manual.
Info: When the router’s Aux Relay automatically activates using the Auto VDC or
AUTO VDC (BTS Comp) setting, the DC voltage is based on the DC voltage reading
from the System Home screen.
• Auto Fault – This setting causes the router’s Aux Relay to stay open during normal operation,
but closes when an inverter/charger fault is detected (see Section 5.3.4 “Fault Mode Messages”
for a list of inverter/charger faults).
Note: The router’s Aux Relay re-opens when the fault is cleared.
• Auto SOC – Automatically activates the router’s Aux Relay based on adjustable SOC settings
under the SETUP: 01G ARTR Relay SOC menu. The relay uses the Close and Open SOC
settings to close and open based on the battery SOC, and allows the relay to be con fi gured
to activate either as an active high or active low type relay. (Refer to the SETUP: 01G ARTR
Relay SOC menu on page 25 for more information on these settings.)
Info: The Auto SOC feature requires the optional ME-BMK (battery monitor) to be
installed.
CTRL: 05 PT Control
The PT Control menu is used for determining how the PT-100 controller charges the battery bank,
how the PT Aux Relay(s) function, and how often you want the PT to sweep for the MPPT. For
information on these settings, refer to Section 12.2.1.
